Claims.

;This invention relates to an article of manufacture, a window curtain or a window curtain section.

The invention has for its object to provide, in

amanner as hereinafter set forth, an article of the type referred to having an integrally woven hem.

A further object of the invention is to provide, in a manner as hereinafter set forth, an article of the type referred to having an integrally woven hem formed with a reinforced outer longitudinal edge.

7 A further object of the invention is to provide,

in a manner as hereinafter set forth, an article of the type referred to having a pair of spaced integrally woven hems with the bends thereof reinforced. V

A further object of the invention is to provide, in a manner as hereinaftergset forth,'an article of the type referred to including a fabric body having a woven hem formed from superposed stretches of the weft threads of the body and with each stretch having interlaced therewith warp threads arranged in parallel pairs.

A further object of the invention is to provide, in a manner as hereinafter set forth, an article of the type refe'rred'to including a fabric body formed of an intermediate part and a pair' of spaced parallel tubular parts forming lateral'continuations of the intermediate part providing Woven hems.

A further object of the invention is to provide, in a manner as hereinafter set forth, an article of the class referred to having a woven hem thereby'eliminating a lengthwise raw edge and which will launder better than a hem formed by a folded-over portion of the body of the article and with the fold anchored by a row or rows of stitching.

further object of the invention is to provide, in a manner as hereinafter set forth, an article of the type referred to including hems at its sides free of sewing threads and the puckering of these latter whereby the article will be straighter and hang better.

A further object of the invention is to provide, in a manner as hereinafter set forth, an article of the type referred to with an integrally formed woven hem.

JA further object of the invention is to provide,

in a manner as hereinafter set forth, an article of the type referred to with an integrally formed woven hem thereby eliminating the use of extra threads and the necessity of removing selvage, as

. well-as overcoming the disadvantages'epresent in a hem which is sewed on ma sewing machine, as the sewing threadsof such type of hem will pucker and have raw edges which will fray.

To the above ends essentially and to others which may hereinafter appear, the invention consists of the novel construction, combination and arrangements of parts as will be more specifically described and are as illustrated in the accompanying drawing wherein is shown an embodiment of the invention, but it'is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed.

In the drawing:

Figure 1 is a front elevation of the article of manufacture in accordance with this invention,

Figure 2 is a fragmentary view, in plan, broken away and upon an enlarged scale, of the article, Figure 3 is a fragmentary view in vertical section, broken away and upon an enlarged scale illustrating the outer side hem of the article,

" Figure 4 is a section on line 44, Figure 2,

Figure 5 is a section on line 55, Figure 2, and Figure 6 is a fragmentary view in perspective and upon an enlarged scale illustrating the inner side hem of the article.

' The article is formed of an open woven fabric body I, but it is to be understood that the body I may be closely woven, preferably it will be open woven whereby the sides thereof will have a hem-stitched effect.

The body I includes an intermediate portion 2, an outer side portion 3, an inner sideportion 4, a top portion 5 and a bottom 6.

The body I is formed from a single group 1, a pair of superposed groups 8, single groups 9, H), H, l2, [3, a pair of superposed groups l4 and a single group I5 of warp threads and said groups interlaced with a Weft o-r filler thread IS. The warp threads of the groups I and I5 are of a greater number than the number of threads of the group-s 8, 9, [0, I2 and I3. The warp threads of the groups 9, l2 and I3 are of a greater numher than the number of threads of the group ID. The number of the threads of the group II are materially greater than the number of the threads of any one of the other of said groups. The number of the threads of each of the groups 8 is less than the number of the threads of either of the groups I4. The threads of groups I and l 5 are closely arranged. The threads of the groups 9, I0, l2 and I3 are closely arranged.

The distance between the threads of the groups 8 is greater than the distance between the threads of the groups I, 9, I0, [2, l3 and I5. The distance between the threads of the group II is greater than that between the threads of the groups I, 9, I0, I2, I3 and I5. The distance between the threads of the groups I4 is greater than that between the threads of the groups 'I, I0, I2, I3 and I5. The distance between the threads of the groups 8, II and It is substantially the same. The group 'I is arranged at one of the longitudinal edges of body I. The group I5 is arranged at the other longitudinal edge of the body I. The group 'I is arranged at the outer side and the group 9 at the inner side of the groups 8. The group I9 is arranged .at the outer side and the group |2 at the inner side of the group II. The group I2 is arranged at the inner side and the group I5 at the outer side of the groups l4- The groups 9 and H] are arranged in parallel spaced relation. The groups I2 and I3 are also arranged in parallel spaced relation.

The weft or filler thread I6 extends alternately in opposite directions with respect to the warp threads. The reversal of direction of the weft or filler thread provides bights which constitute the side edges of the curtain. Extending of the weft or filler thread I5 alternately in opposite directions provides it throughout with parallel pairs of oppositely disposed portions termed strands. The strands of each. pair are disposed in outwardly and inwardly relation with respect to each other and arranged in superposed relation. The outer strand .of each pair of strands of the thread I6 is formed of an elongated intermediate stretch I'I, an outer end stretch I9 of lesslength than and merging at its inner end into one end of the stretch I1 and an inner end stretch 2| of greater length than the stretch I9, and of less length than and merging at its inner end into the other end of the stretch H. The inner strand of each pair of strands of the thread I6 is formed of an elongated intermediate stretch IS, an outer end stretch 29 of less length than and merging at its inner end into one end of the stretch I8 and an inner end stretch 22 of greater lengththarr the stretch 20 and of less length than and merging at its inner end into the other end of the stretch I8. The stretches II, I8 are of like length. The stretches |9-, 20 are of like length and the stretches 2|, 22 are of like length. Bights 23 connect the outer ends of the stretches I9, 20 together and bights 24 connect the outer ends of the stretches 2|, 22 together. The stretches I], I8 are arranged in abutting relation. The stretches I9, 29 are arranged in superposed spaced relation. The stretches 2|, 22 are arranged in superposed spaced relation. The groups 9, II], II, I2, I3 of the warp threads are interlaced with the stretches I'I, I8. One of the groups 8 of the warp threads is interlaced with the stretch I9 and the other group 8 of the warp threads is interlaced with the stretch 29 of the weft threads. One of the groups I4 of the warp threads is interlaced with the stretch 2| and the other group I4 of the warp threads is interlaced with the stretch 20 of the weft threads. The group 'I of the warp threads is interlaced with stretches |9, 2|] and bights 23 of the weft strands. The group I5 of the warp threads is interlaced with the stretches 2|, 22 and bights 24 of the weft strands. Those threads of the group 1 which are interlaced with the bights 23 are closely related whereby one lengthwise edge of the curtain is reinforced. Those threads of the group I5 which are interlaced with the bights 24 are closely related whereby the other lengthwise edge of the curtain is reinforced.

The stretches I9, 29 and bights 23 of the weft strands in connection with the groups I and 8 of the warp strands provide an integrally woven tubular hem 25 at the outer side of the body I and with the group 1 of the warp threads forming a reinforced outer longitudinal edge for the hem 26.

The stretches 2|, 22 and bights 24 of the weft strands in connection with the groups I4 and I5 of the warp threads provide an integrally woven tubular hem 25 at the inner side of the body I and with the group I5 of the warp threads forming a reinforced inner longitudinal edge for the hem 26.

As the stretches I9, 20 of the weft strands are of less length than the stretches 2|, 22 of such strands the hem 26 is of greater width than the hem 25.

One end terminalportion of the stretches II,

I8 in connection with the group of threads 9- provide for the closing of the inner side of hem 25 without the employment of a stitching. The outer side of hem 25 is closedby the bights 23 and threads I. The other end terminal portion of the stretches |'I, I8 in connection withthe group of threads I3 close the inner side of hem 26 without the employment of stitching. The outer side of hem 26 is closed by the bights 24 and the threads l5.

The top and bottom, 5 and 6 respectively of the article are reinforced. The top 5 is formed by folding inwardly one of the end terminal portions of the body I and anchoring suchend terminal in its folded position. The bottom 6 is formed by folding inwardly the other end terminal portion of body I and anchoring such end terminal in its folded position.
